“…Isto confirma o potencial do resíduo como fonte de potássio para soja. O acúmulo de potássio no tecido vegetal também foi verificado por Nascimento et al (2017) quando aplicou vinhaça no cultivo de alfafa. O aumento de potássio na planta é importante para o sistema de produção pois o potássio apresenta alta mobilidade e não faz parte de nenhum composto orgânico na planta.…”

ResumoA vinhaça é um resíduo orgânico líquido proveniente do processo de fermentação para obtenção de substâncias alcoólicas, principalmente o etanol. É rica em potássio, nutriente essencial para o desenvolvimento da soja. A vinhaça é um resíduo classe II (não perigoso) caracterizado pela ausência de metais pesados e contaminantes patogênicos, por isso pode ser utilizada como biofertilizante em diversas culturas agrícolas. Objetivou-se através do presente trabalho estudar o efeito da aplicação de vinhaça na forma "in natura" e "concentrada" como fonte de potássio em substituição parcial e total na cultura da soja. O delineamento experimental utilizado foi o de blocos ao acaso, com quatro repetições. Os tratamentos foram distribuídos em função das condições da vinhaça (in natura e concentrada), aplicado na semeadura e em cobertura quando associado com a adubação mineral com cloreto de potássio na semeadura. No primeiro ano de cultivo a utilização da vinhaça promove melhores condições para nodulação e crescimento da planta. A vinhaça não afeta a nodulação da soja nos dois momentos de aplicação (semeadura e cobertura). A vinhaça pode ser utilizada como biofertilizante em substituição parcial ou total da adubação mineral com cloreto de potássio em soja, independentemente de sua forma de aplicação (in natura ou concentrada).

Vinhaça as a biofertilizer in soybean culture: effect on nodulation, growth and nutrient aculmulation AbstractVinasse is a liquid organic waste from the fermentation process to obtain alcoholic substances, mainly ethanol. It is rich in potassium, essential nutrient for soy development. Vinasse is a class II (non-hazardous) residue characterized by the absence of heavy metals and pathogenic contaminants, so it can be used as biofertilizer in various agricultural crops. The objective of the present work was to study the effect of application of "fresh" and "concentrated" vinasse as potassium source in partial and total substitution in soybean crop. The experimental design was a randomized block design with four replications. The treatments were distributed according to the conditions of the vinasse (fresh and concentrated), applied at sowing and covering when associated with mineral fertilization with potassium chloride at sowing. In the first year of cultivation the use of vinasse promotes better conditions for nodulation and plant growth. Vinasse does not affect soybean nodulation at both application times (sowing and mulching). Vinasse can be used as biofertilizer in partial or total substitution of potassium chloride mineral fertilization in soybean, regardless of its application form (fresh or concentrated).

“…S. G. Silva et al (2017) investigated the nutritional status of sugarcane varieties and found higher average K levels in the TVD leaf of the crop than Ca and Mg. According to Nascimento, Souza, Moreira and Moraes (2017), vinasse doses applied to the soil increase the K content of plants, but can reduce their Ca and Mg levels.…”

Vinasse, a waste from ethanol production, has been widely used as a means of fertigation in sugarcane. However, high dose limits application at and its effects on nutrient absorption and accumulation by the crop are not known. The aim of this study was to evaluate and compare, during the initial development of sugarcane, the effect of mineral fertilization and high doses of vinasse on the macronutrient and sodium contents of the top visible dewlap (TVD) leaf and their respective accumulations in the aerial part of the crop. The experiment was carried out in 100-dm3 pots filled with Argisol. The treatments consisted of five doses of vinasse (0, 150, 300, 600 and 1200 m3 ha-1) and an additional treatment with no vinasse and mineral fertilizer (500 kg ha-1 of the NPK 14-24-18 formulation). The levels of nitrogen, phosphorus, potassium, calcium, magnesium and sodium were evaluated in the TVD leaf at 120 days after planting and their accumulation in the aerial part of the plant at 210 days. Data were subjected to analysis of variance and compared using regression analysis and orthogonal contrasts. The vinasse doses applied did not adequately nourish the crop in macronutrients. Mineral fertilization provided higher N and P levels. The highest doses of vinasse provided higher levels of K, Ca and Mg and larger accumulations of N, P, K and Na, but were detrimental to the accumulation of Ca. The descending order of accumulation of macronutrients and sodium with mineral fertilization was P> Ca> N> K> Mg> Na. For the application of vinasse, the descending order was K> P> Ca> N> Na> Mg. In the absence of mineral fertilization and vinasse, the descending order was P> Ca> K> N> Mg> Na.

“…Gypsum is a known source of calcium (Ca) and sulphurum (S) for plants, and from 200 to 300 kg ha -1 is sufficient to meet annual requirements of most agricultural crops (Sousa et al, 2007). Gypsum can increase Ca and sulphate ) availabilities within surface and subsurface soil layers when applied at high rates (Rentería-Villalobos et al, 2010) and it could be noted that gypsum has also diminished aluminium (Al) toxicity in these soil layers without changing soil pH (Araújo et al, 2016;Nascimento et al, 2017). Thus, gypsum can be considered a good source of Ca and S, and also able to alleviate aluminium (Al) toxicity in soils.…”

Gypsum can be used as a source for calcium (Ca) and sulphurum (S) for plants, as well as an acid, that is, a natural soil conditioner. Aiming to determine the influence of gypsum on the development of Eucalyptus urograndis in Brazil, an experiment was conducted at two locations in Paraná State. Experiments were conducted with rates of 0, 0.3, 0.6, 1.2, 2.4, 4.8 and 9.6 Mg ha-1 to verify the method of broadcast planting in a randomized block design with four repetitions. Diameter and height of plants were measured every six months and volume was determined after 36 months. There was a difference in Eucalyptus growth between the two areas, possibly related to differences in planting season and climate. Gypsum did not influence on the dendrometric growth of Eucalyptus trees. The lack of a response to gypsum, as a source of Ca, S and soil conditioner, was discussed based on soil type, Eucalyptus tolerance to soil acidity, and climatic conditions in the period evaluated.
